Using SP LINK

Overview

“SP LINK is the pathway to the real power of the SP PRO AU and GO” SP PRO AU and GO series of inverters are really many products in one. Simply unpack the unit, mount it on a wall, connect the appropriate cables – and you’ve got power using the following default settings; • Off Grid • AC Source size is equal to the power output of the SP PRO model you are using • Sealed Batteries • No State of Charge readings, voltage only.

To go further and unlock all the features of the SP PRO simply load the SP LINK software (found on the supplied USB stick or download from www.selectronic.com.au) onto a PC computer. We suggest these steps are done before heading to the installation site.

Getting Started with SP LINK

You will find SP LINK and other helpful documents contained on the USB stick supplied with the SP PRO, it is good practise to check at www.selectronic.com.au for the latest version of SP LINK.

After loading SP LINK onto the computer, you can now begin to use SP LINK. However, we do warn that to achieve the best performance from the system, configuration should be done by an experienced system designer. For maximum warranty in Australia, you will need to employ the services of a Selectronic Accredited Integrator. For full warranty terms and conditions please see the warranty supplied with the SP PRO inverter.

To get started, you do not have to be connected to an SP PRO inverter. Once you have loaded SP LINK onto the computer, you can pre-configure and store on the computer the site information and configuration settings. These are then ready to transfer into the SP PRO inverter after it is installed.

When you first open SP LINK, the Splash screen will appear. Once SP LINK has loaded, the screen will disappear and the “How to Access Help” screen will appear.

HELP!

When working with SP LINK simply RIGHT CLICK MOST HEADINGS and tabs and a help panel will appear on the right side of the screen.You will see the How to Access this Help guide each time you start SP LINK

By clicking “Continue” SP LINK Easy Start Guide will start. By clicking the tick box “Don’t show me this screen again” will prevent this from being displayed in the future.You can also access both the SP PRO manual and SP LINK manual (this document) from the Help menu at any time.

Site Configuration Wizard

Provides a quick and easy way to configure a SP PRO in a new installation. The configuration information can be created and saved to a Site file ready for sending to the inverter as required.

The wizard steps through the configuration process and informs the system designer at each step of any invalid configuration or limitations of the chosen components.

The wizard is self explanatory. A description of each screen is given below

New Site Configuration Details

Enter a unique and descriptive name for the site where the SP PRO is installed. This name will be used to store and retrieve the information at a later date.

Select a Detected USB Device: If the computer USB port is plugged into a SP PRO that is powered up then its model number and serial number will be displayed. Select the inverter to configure

Manual Configuration :If there is no SP PRO connected then click on either the SP PRO AU or SP PRO GO image then select model number.

Select Battery Configuration

If a myGrid kit is installed in the system then select myGrid Energy Center and select the model number.

Otherwise select Custom Battery Configuration to manually enter the battery information. If the system is a batteryless configuration then select No Battery Installed (this option is only valid for SP PRO GO models and requires a optional Batteryless kit.)

Once the battery type is chosen the battery State of Charge levels are chosen (except for No Battery option).

SoC Support Limit (Support Capacity) sets the energy that is available for normal daily operation. If the system is Off Grid with an auto start generator, then this is the SoC level at which the generator will start This value is dependant on the battery type and its expected cycle life.

Inverter Shutdown SoC (Minimum Backup Capacity) sets the energy available during either a grid outage (for Solar Hybrid) or when the generator fails to start (for off grid)


Doc #OI0005 Rev13 2016 | 9

Source of RenewablesSelect the configuration of the Solar or other renewable energy sources in the system. The wizard will provide information on the power limits of any energy source as they are selected.

Where Managed AC Coupled Solar is selected, either KACO or ABB grid inverters may be selected. Whilst the SP PRO is connected to grid power, the maximum allowable Managed AC coupled solar power is only limited by the selected SP PRO model. When the SP PRO is running Islanded (either the grid has failed or the system is an Off Grid system), the SP PRO will limit the maximum solar power that can be produced by the KACO or ABB grid inverters. This limit which is determined by the system battery capacity as displayed on the screen.

If the energy source is DC coupled (that is fed into the battery via a DC charge regulator or DC MPPT) then an external DC current shunt must be installed.

Select Unit ApplicationThe first three options are for grid connected systems and are applicable to both the SP PRO AU and GO series. The Off Grid Option is only applicable to the SP PRO AU.

When Self-Consumption of Renewables is chosen the system will do a full recharge once per week. Its time can be changed to coincide with the period of lowest tariff and at a time when the renewable would have performed a full charge when available.

Summary of SettingsThe next screen gives a summary of all the settings entered to allow a final check before the configuration is created Clicking Finish will complete the wizard, update the configuration settings in SP LINK and return to the Site Information and Connections Settings screen in Advance Configuration.

.

Entering extra Details and Saving Any further site information and connection settings may now be entered. If any of the advanced settings need configuring then this should also be done now. Once all the information has been entered and the configuration is complete the Site file along with the Configuration details can be saved to file using the File/Site Information/Save menu (or hit CTRL S key).

Sending Configuration to the InverterThe configuration is now ready to transfer to the SP PRO. First of all plug the computer into the inverter using the supplied USB lead then click the Connect button in the Connection Settings. Once connected select the Configuration Settings tab and click the “Configure SP PRO” button.

See Saving a New Site and Connection Settings sections for more information.

Advanced Configuration

Advanced configuration gives access to all the functions of SP LINK allowing the installer to create a Site file and manual configuration that starts with either the default settings or settings created from the Site Configuration Wizard.

The Quick View and Data View tabs read all the information from the connected SP PRO to assist the installer in commissioning and diagnosing the System. Please remember that if help is require for a function in SP LINK hover the cursor over the heading or right click on the heading to be taken to the relevant section of the SP LINK manual.

Preparing a new site

SP LINK Advanced Configuration will open in the Site Information tab. Information must be entered in the mandatory fields with red stars including information in the lower tabs. Also it is not possible to proceed without setting up and saving the site information into a Site file.

There is a large window on the right side of the Site Information page, click here to place a photo of the system

To create a new site file for Series I units, click on Convert to Series I and then proceed with remaining steps.

For backward compatibility for SP PRO firmware version prior to 7.0, tick Show legacy settings option. SP LINK will also automatically detect this upon connection to a SP PRO unit with firmware prior to 7.0.

It is also helpful to place photos of the various system components under the Components tab.


Doc #OI0005 Rev13 2016 | 11

Under Connection Settings please select the Connection Type method to connect to the SP PRO. To connect directly to the USB port of the SP PRO select USB. The model number/serial number of the SP PRO to be connected to can now be selected from the list

A Login Password is required for connecting to the SP PRO. SP LINK can only connect with the correct password. The default password is “Selectronic SP PRO”.The Login Password is different to the Setting Passcode.

The Login Password only needs to be changed if you wish to prevent any connection to the SP PRO. This is particularly important to secure the SP PRO against unauthorised monitoring or modification when the SP PRO is remotely accessible via a Modem or Network connection type. Once connected, the default password may be changed under Service Settings. If the Login Password is lost or forgotten it can only be reset by a procedure that requires someone to be on site. Contact a Selectronic Accredited Integrator.

Saving a new site

All site information must now be saved.

To save the SP PRO site information, click on File - Site Information - Save.

As this is a new site you will need to chose a common place on the computer to store the site folder, other information about this site such as Performance Downloads and Configuration settings will automatically be placed in this folder, the folder will have the same name as the site. Site files will be named with a .SPLS extension.


12 | Doc #OI0005 Rev13 2016

Manually Preparing a new configurationYou can now start to prepare a manual configuration. The SP PRO configuration is stored in a file within the site file and contains all of the SP PRO settings for transferring into the SP PRO when connecting via SP LINK.

Click on the Configuration settings tab.

The SP PRO is a very advanced and intelligent product but don’t let the large number of settings concern you.

The default configuration settings have been carefully considered and will be adequate in most circumstances. The Site Configuration Wizard can be use to set up the standard configurations before setting any advanced functions.

There is a Quick Start section near the top of the page which contains the settings that need to be considered for all applications.

The following table indicates the settings needed to be considered for each system. Most of these configurations are included in the Site Configuration Wizard

Saving a new configurationThe configuration settings should now be saved to file before sending them to the SP PRO.

To save the SP PRO configuration settings, click on File - Configuration Settings - Save.

The configuration settings will be saved in the same location as the site information saved in the previous step. SP LINK will automatically use the default file name Config1 prefixed with the site name.

The configuration settings are now stored on the computer. The SP PRO can be configured with these settings at any time once the computer is linked and connected to the SP PRO.

Connecting to the SP PROPlug the SP PRO into the computer with the supplied USB cable. The SP PRO will be automatically detected by the computer and SP LINK. When this occurs it will be indicated by SP LINK showing both model and serial number under Connection Settings.

Now we can connect to the SP PRO. Either clicking the Connect button, in the Connection menu, click Connect or double click the connection status bar (1)

SP LINK is now connected through to the SP PRO. SP LINK will notify you if a connection is unable to be established.

It is important to note that the SP PRO has NOT yet been configured with any of the setting changes made at this time. This is performed in the next step.

SP LINK will notify you if the connected SP PRO does NOT have the same model number and serial number as detailed in the SP LINK “SP PRO Details” tab. SP LINK will also prompt you, as required, to update the time within the SP PRO from the computers time.


Doc #OI0005 Rev13 2016 | 15

Configuring the SP PRO

With SP LINK connected to the SP PRO, Click “Configure SP PRO” from the File - Configuration Settings menu or the button on the Configuration Setting page.

SP LINK will - unless “Configure SP PRO” has just been performed - warn that all settings will be overwritten.

For security purposes, to ensure no-one can tamper with the SP PRO, you will now be asked to enter the passcode. This passcode will remain active until the SP PRO is disconnected and will not need to be re-entered until the next connection session.

The default passcode is 74, however you can alter this if you wish. We will cover altering the passcode when we get to “Service Settings”.

Once you have entered the passcode click “OK”

SP LINK will verify passcode and configure the SP PRO with these changes.

SP LINK will indicate if for any reason the Configuration was unsuccessful.

You have now transferred all the Configuration Settings shown in SP LINK into the SP PRO. The settings take immediate effect and can be performed with the SP PRO fully operational.

To avoid unexpected operation, the SP PRO is prevented from turning on until a configuration setting has been saved by clicking “Configure SP PRO”. The ON LED on the front panel will flash red until the SP PRO has been configured for the first time or after a reset to factory defaults.


16 | Doc #OI0005 Rev13 2016

For Modem connections, select the PC COM port that the modem is connected to. Enter the Modem Phone Number. This is the number that SP LINK will dial when you select Connect. Modem Initialisation can be left blank when using Selectronic supplied modems but may be required for other modem types.Consult the modem supplier if unsure.

Connection SettingsThe connection settings allow other connection types as well as USB Direct. The connection settings need to be set depending on which other communication method is being used. Details for all connection types are stored with the site allowing multiple connection methods to be retained in one site file.

Login PasswordA Login Password is required for connecting to the SP PRO. SP LINK can only connect through to the SP PRO with the correct password. The default password is “Selectronic SP PRO”. This is different to the setting passcode.

Modem - Remote dial-up connection.

Network - IP connection.For Network connections, enter the Hostname or IP Address of the serial/Ethernet adaptor and the IP Port number of the serial connection to the SP PRO.Note: Using network connection requires thorough knowledge of IP networks and router configuration and data encapsulation. SP LINK communicates in RAW format to the set IP port via with no embedded serial/Ethernet device control. All data sent and received by the serial/Ethernet device must be passed through. Serial/Ethernet device must be set to match the port speed of the SP PRO.

Use Direct connection Type when using a RS232 serial connection. Once all cables are connected and in place, press Find SP PRO - this will search through all PC ports and find the connected SP PRO and set connection parameters.

Use Wireless when connecting via a RS232 wireless device. This setting operates similar to Direct but allows for the extra delays normally present in a wireless link

Direct and Wireless - Local connection.

SP LINK will automatically detect and list all SP PRO inverters plugged into the PC via their USB ports. Select the SP PRO to connect to and hit the CONNECT button.

Consult the installation guide supplied with the Ethernet adaptor or an IT specialist for further information.

Customising SP LINK to suit the site

The SITE INFORMATION screen on SP LINK allows you to record specific site details that are individual to the installation, such as the Site name, the System Integrator, the inverter Serial Number as well as including a photo of the site.

In the SP PRO DETAILS screen you can choose from earlier saved configuration files. As an example, you may have two sets of settings for the inverter saved within SP LINK; one for NORMAL everyday use, and one for HOLIDAY use. In the holiday file you may have included automatic garden watering, switching security lights on and off or even switching off the inverter for periods of time. Changing these settings is as easy as browsing the saved files through the FILE - SITE INFORMATION - ASSOCIATE EXISTING CONFIGURATION menu option or clicking Associate Existing Configuration and selecting the appropriate configuration then clicking on OPEN. This will now load in those settings ready to be Configured into the SP PRO.

The SP PRO series are very advanced and intelligent products with a large number of settings to suit virtually any application. By default, the SP PRO will run as an off-grid inverter charger and through enabling additional features within the SP PRO, many differing system objectives can be achieved. At this stage you can choose to either start a new configuration using the default settings OR use the Site Configuration Wizard to setup a more advanced starting point.

The Configuration Settings are divided into named sections indicating the types of settings within them. Each tab highlights a different configuration area within the SP PRO. To access these settings, click on the various section tabs.

Settings can be changed by either clicking on the drop down list or directly changing the value. Every time you change a setting the title of that setting becomes highlighted in yellow. This is to remind you that you have changed this setting. This highlight disappears when you either save the configuration to file or the SP PRO.(Hit “Configure SP PRO” button).

The following pages detail each tab and individual setting contained within.

Configuration Settings


Doc #OI0005 Rev13 2016 | 21

Unit Application determines how you will use the SP PRO.• Off Grid for remote area homes where a backup motor generator will be used and no

grid connection is available. (SP PRO AU ONLY)• Mobile for Motor homes, Caravans & Boats (SP PRO AU ONLY)• On Grid (Solar Hybrid) where you wish to feed Solar, Wind or Hydro power to the

electricity grid. Use this setting for Self Consumption of the Solar or Wind power whilst providing back up power as required.

Battery Type programs the SP PRO with the appropriate default charging parameters.The default parameters will be suitable for most battery brands but to ensure maximum battery performance and life, please refer to the battery manufacturers recommendations when programming Battery charging parameters. (Charger tab).

IMPORTANT: When using Lithium Battery or similar technologies with the SP PRO inverter, the battery bank MUST be fitted with a Battery Management System (BMS) that monitors and fully protects the battery bank. The BMS MUST have its own independent disconnect that will fully isolate the battery bank from the system in the event of an adverse or alarm condition.

Batteryless (SP PRO GO ONLY with optional Batteryless kit) allows the SP PRO GO to operate without a battery bank. The SP PRO GO is powered from an internal power supply via the AC source input. When in this mode all battery functions including Charging, Load support and backup power are disable and the inverter will remain in “Idle”. All settings are disabled with the exception of Alarm, Communication and String Inverter (in System Tab).

AC Source Power configures the maximum allowable power drawn from the AC supply whether it be from a grid supply or motor generator set. Using the right hand drop down menu choose kW, kVA or Amps. The setting will scale accordingly The SP PRO will try and keep its power draw below this value and will only exceed it when the load is greater than the inverter capacity plus this value.

State of Charge (SoC) control gives you the option of controlling the system with either a calculated state of charge or by the battery voltage. It is important to note, that for State of Charge control to operate correctly, the SP PRO must be able to read and monitor any charge or discharge of the battery, external to the SP PRO. External current shunt will need to be installed for all DC charging sources of DC loads. Currents shunts are configured under the “Shunts” tab. The SP PRO does NOT need a shunt for it’s own battery current or for any installed AC coupled solar.I

Enabling State of Charge Control provides greater flexibility in system programming and will allow the battery indicator on the front of the inverter to display usable charge in the battery like the fuel gauge in your car. If State of Charge is disabled the battery indicator will show the battery voltage from the Low DC Shutdown level (no LEDs on) to the Float Charge Voltage level (all LEDs on).

Battery capacity is used by the SP PRO to calculate the battery’s State of Charge. To determine the Battery Capacity first determine the approximate average C rate that the batteries will be discharged over a day. Then use the battery manufacturers specification to determine the battery capacity at this C rate For example, if the batteries are slowly discharged (such as a typical off grid system) then it is likely you would use the C100 or C120 rating, if the batteries will be discharged quickly (typical Solar hybrid system) then likely the C10 - C20 rate.NOTE: It is safest to use a lower value of battery capacity if unsure

Quick StartThe Quick Start section provides the settings needed to be considered for all applications.


22 | Doc #OI0005 Rev13 2016

Inverter Settings

The Inverter tab shows the output settings and minimum battery levels for the inverter to operate within.

With Econo Mode disabled the inverter will run continuously with no AC load. When Enabled, the SP PRO will go to “sleep” when the AC load power is below the Econo Transition Level for more than 30 seconds. It will “wake up” again and run the load once the AC load goes above the Econo Transition level. A short push of the ON button is also required to enable Econo Mode (ON LED slowly flashing Green).Econo Transition level is normally chosen to reflect the smallest load that is required to start the inverter, i.e. You may choose 20 watts if you want the inverter to start when you switch on a lamp or you may choose 5 -7 watts if you want it to turn on with a ‘phone charger’.

In Econo Mode the inverter puts out pulses of power (100mS wide) to sense the load power. The frequency of these pulses is adjusted by setting the Econo Pulse Period. e.g. If set to 0.5 s, the SP PRO will output a pulse every 0.5 seconds

Econo mode can only be enabled for single phase, DC coupled Off Grid configurations of 24 V and 48 V models. This feature is disabled for all other configurations including managed or generic AC coupled solar. If you have loads that require power 24/7, DO NOT enable Econo mode.

Inverter Output sets the Nominal AC Voltage and the Nominal AC Frequency of the inverter. For example, in Australia this is 240 volts and 50 Hz.

When an SP PRO is being used in an “Solar Hybrid” application reference to the local grid supply voltage should be considered as this sometimes varies from the national standard. If unsure then consult the local power authority.

Nominal AC Frequency is set to 50Hz and cannot be changed when Powador Managed AC Coupled Solar is enabled. When ABB managed AC coupling is enabled, then 50Hz or 60 Hz may be selected


Doc #OI0005 Rev13 2016 | 23

Support Power Factor. This setting is configured when the SP PRO is installed as a Solar Hybrid (grid connected) system and the inverter is required by the Utility to provide support power at a non-unity power factor. Set the value of the required power factor and the phase of that power factor. Whenever the SP PRO is supporting the load from the battery, the supplied support power has a constant power factor according to this setting

Charge Power Factor. This parameter sets the power factor of the power being taken from the AC source when the SP PRO is charging the battery bank. Unless there is a special design requirement for this setting it is always left at 1.000.

DC Shutdown uses battery voltage to control how far the batteries will discharge before the inverter will switch itself off. These settings are important as discharging batteries too far can make them hard to recharge or even damage the batteries.

The first setting Battery 0% Load is the voltage at which the inverter will shutdown with no load applied to the battery including any DC loads. The second setting Battery 100% Load is the shutdown voltage when 100% battery load is applied. 100% battery load is when the battery current is equal to 20% of the battery capacity (C/5). When the battery load is between these two levels the SP PRO will calculate a shutdown voltage based on these two voltages.

Battery load is only the energy coming from the battery. As an example, in an AC Coupled system with no AC source, 2 kW of AC Load and 2 kW of solar there will be NO load on the battery so the DC shutdown will be at the Battery 0% Load voltage .

Recovery Voltage When the inverter shuts down due to low voltage this setting allows you to determine the voltage at which the inverter will start up again. It is wise to make this voltage high enough to ensure that sufficient recharging has occurred before the inverter turns on again.

SoC Shutdown.(Only available when SoC Control is Enabled) Programs the inverter to shutdown in response to the state of charge of the battery. When enabled the Shutdown SoC can be set anywhere between 0 and 100%. For a lead acid battery this will generally be 40-60% but confirm this with the battery supplier.

In a well designed Off Grid system the batteries should only get to the Shutdown State Of Charge during a fault condition (e.g. Generator failed to start).

For a well designed Solar Hybrid (On Grid) system the Shutdown SoC would only be reached during a grid outage.

The Shutdown SoC setting also determines the lowest reading (one LED on) of battery indicator display on the front panel of the SP PRO.

Max Voltage Limit is the absolute maximum voltage produced by the charging section of the inverter in any charge stage.

Hi Battery Alert initiates an alarm when the battery voltage exceeds this level. When either “Generic AC Coupling” or “String Inverter” has been set (in System tab. See page 24) this setting has an additional protection function. When the Hi Battery Alert voltage has been exceeded for a few seconds indicating a fault in the AC coupled installation, the SP PRO will ramp the frequency of its AC output to 55Hz to disconnect all connected AC coupled grid inverters thereby removing all AC coupled charging sources.

When the battery voltage falls to the value set in Hi Battery Alert Clear the alarm stops.

Instant Trip AC Coupling is the battery voltage at which the SP PRO will instantly trip any Managed AC coupled Solar to zero output. This setting is used for Lithium battery or similar technologies that have an absolute maximum battery charge voltage.

Periodic Equalise. Battery banks used in cyclic applications may, over time develop charge (and voltage) imbalances and may require an “equalise” charge . How often an equalise occurs is set using Equalise Period. The equalise charge voltage, current and duration are set in the CHARGER tab. (See “Charger Settings” section)

When an equalise charge is carried out by a charging source that is external to the SP PRO (i.e. DC coupled solar or wind sources) the SP PRO monitors this and reschedules its equalise. For the SP PRO to reschedule, the battery voltage must be taken to or above the EQUALISE STAGE voltage for the EQUALISE TIME settings in the SP PRO therefore it is important to match or slightly exceed these setting in the external renewable controller.

Periodic Recharge is for systems that remain on Float charge for long periods of time such as Solar Hybrid or Boats in Marinas. Battery banks operating in these conditions benefit from periodically being put through a full charge process. When enabled, after remaining in Float for the number of days set by the Recharge Period, the SP PRO will return to Initial charge stage.

Soft Battery setting is used with battery banks that are “soft” meaning they have a relatively high internal impedance. Useful with aqueous type battery technologies or battery banks with high internal impedance.Technically this function is achieved within the SP PRO by reducing the gain of the battery charger’s voltage control loop thereby increasing the damping of said loop. Soft setting reduces the gain to 50% whilst Very Soft to 25% of the normal value.NOTE: This setting is only effective with battery technologies that have an inherently high internal impedance such as aqueous type technologies. Using this setting with serviceable lead acid or lithium battery technologies may cause unintended charger operation and in some cases over voltage shutdowns.

Battery Settings

The Battery Tab contains settings intended to protect and maintain the batteries. Please note that you must comply with the requirements of the batteries specifications, failure to do so may void the battery warranty. When in doubt, consult the battery supplier.

Charger Settings

This tab shows all the settings relating to the DC voltages and currents used in the battery recharge stages.

The normal charge cycle involves a four stage charge – Initial, Bulk, Absorption and Float– while periodically it is necessary to go one stage further, for the performance and longevity of the battery bank, to the Equalise stage. We will describe each of these stages as we progress. Please note there is a slider at the bottom of this page to move to more settings as this section is quite extensive.

Mid Point Monitoring is a function designed to highlight any significant voltage variation between one half of the battery bank and the other. If one half of the bank is lower than the other it may suggest that the batteries need an equalisation charge or, perhaps, that there is a cell in one half that is not performing correctly. In Mid Point Range you determine how much variation between the two halves you will allow before notification. With this function you can help predict battery problems. To make use of this feature you will need to install an additional wire to the battery, see installation section for details. We recommend the use of this handy feature.

Often these problems can be solved by an equalisation charge so we have included provision for you to request such a charge by enabling the Equalise Request setting.

Peukert’s Exponent is a legacy setting and is not required in SP PRO firmware versions 7.06 and greater. The firmware now intelligently learns and compensates for the battery performance resulting in a more accurate SoC calculation.

OVER TEMP. PROTECTION This feature reduces the charge current automatically as the battery temperature rises above the temperature specified in Limit Charge above. It reduces the charge current by the Limit Rate for every degree Celsius that the temperature is above the temperature specified.

With the default settings the charge rate will drop 10% for every degree over 45°C. e.g. no charging current at 55°C.


26 | Doc #OI0005 Rev13 2016

The default charge settings should be considered as safe for most battery types. Exact charging parameters should be confirmed with the battery supplier.

Max. Charge Current is the maximum charge current that the inverter will allow to the batteries under any circumstances (including all external charge currents) at any charge stage. This is expressed as a percentage of the battery capacity. For example if the battery capacity is 900 amp hours and the battery manufacturer suggests a maximum charge current of 10% of capacity then you would set this figure at 10% and the maximum charge current limit would be set at 90 amps. If, in this case there is 40 A of solar charge current, the inverter will add to this a maximum of 50 A of charge into the battery.

Initial Return is the voltage level at which the charge cycle will return to the beginning, or Initial, stage of the charge process. The battery voltage must remain at or below this level for 2 minutes to switch to Initial. This ensures that short term loads do not prematurely cause the charger to reset to Initial. The setting will turn RED when it exceeds the lowest float voltage (either Float or Long term Float) minus 5%. Care should be taken when setting in the RED region to ensure the Float or Long term Float voltages cannot trigger the Initial return under the maximum battery temperature conditions.

The purpose of the INITIAL STAGE of the charging process is to raise the battery voltage quickly with a large charge current. In this section you set the Voltage you wish the batteries to reach, the Current you wish to charge at and the length of Time the batteries will stay at that voltage until the inverter moves to the next stage of the charge cycle.

The current is expressed as a % of the maximum charge current. Using our previous example if the maximum charge current was 90 amps and you wish to charge, in this stage, at ~85 amps you would insert 95 in this area. i.e. 95% of 90 amps = 85.5 amps

BULK STAGE is the part of the charge cycle where the majority of the charging takes place. This is normally set at a higher Voltage than the initial stage but at a lower charge Current. The Time setting determines, once the Bulk Voltage is reached, how long the batteries stay at this level until the inverter starts the next stage of the charge process.

Once again using our example if you wanted this stage to charge at ~80 amps you would insert 90 as the setting because 90% of 90 amps is 81 amps. The time that the charge stage would remain at this voltage would normally be set longer than in the initial stage.

THE ABSORPTION STAGE is the part of the charge process that allows the batteries to maximise the effect of the previous charge stages. This stage is normally set to a higher Voltage than the two previous stages but a lower charge Current The Max Time it would remain in this stage is longer again than the previous stages.

This section has a further level of control in that it will also end this stage and transition to Float if the change in current becomes less than the Net Change setting for a period equal to the Change Time setting. NOTE: When “System SoC” shunt is configured (see Shunt Settings) then the current measured by this shunt type is used for the change in Net Charge.

For example if you have set the absorption Voltage to 57.6 volts, the Current to 60% (54 amps) and the Max Time to 120 minutes, then the battery will be charged at 54 A until the battery voltage reaches 57.6 volts. At this point the battery charging stage will change from Absorption into Float based on which of the following occurs first:1. The rate of change in charge current is low. For example the battery bank capacity is 900 Ah, Net Change is set to 1% and Change Time set to 30 minutes. Transition to Float will occur when net battery charge current has not changed by more than 9 A in 30 minutes.2. The Max Time has expired. This is the maximum time the charger will stay in the Absorption stage after the battery voltage has reached the Voltage setting..


Doc #OI0005 Rev13 2016 | 27

In addition to these stages of charge there are more settings you can access by moving the bottom slider bar.

After completion of the charge cycle the inverter will enter the FLOAT STAGE. This setting reflects a Voltage that the system will maintain, with a good state of charge, for a long period. If the generator continues to run past the absorption or equalise stage for any reason, such as maintaining a high load, the inverter will keep the batteries at the float stage Voltage – not exceeding the Current set – until the generator is shut off. When the generator or mains voltage is present for longer than 24 hours the charger will drop to the Long Term Voltage to maintain a good state of charge for the lowest charge current. This is particularly useful in boating marinas where shore power may be connected for long periods.

THE EQUALISE STAGE is not employed every time the batteries are charged but is a periodic charge process that raises the battery Voltage above the normal voltage settings to a point where the batteries will, essentially be in a state of overcharge. This is necessary to overcome any variations in voltage between individual cells that occur naturally in a battery bank that is cycled between load and charge cycles. These variations can cause a drop in performance in the battery bank and must be “equalised”. In flooded cells this process is sometimes called “gassing”, that is when the batteries sound as if they are lightly boiling. In flooded cells this bubbling helps to circulate the electrolyte fluid within the cells.The Equalise stage will raise battery voltage to the equalise Voltage level and maintain this voltage for the equalise Time. The equalise Current will not be exceeded. If using Sealed batteries, the EQUALISE STAGE may be at the same voltage as Absorption voltage but for a longer period of time. Check with the Battery supplier.

Most lead acid batteries require the charging voltages to change with temperature (Temperature Compensation). The temperature compensation between the Min. Comp. Temp and Reference Temp. A is set in the Ref. A Temp. Co. The temperature compensation between the Max. Comp. Temp and Reference Temp. B is set in the Ref. B Temp. Co. The temperature compensation between the Reference Temp. A and Reference Temp. B is zero and equals the charge voltage setting. Ref. A Temp. Co. and Ref. B Temp. Co sets the charge voltage change in mV per deg C for each 2V cell .

For example using settings in the diagram to the right and assuming a 48V battery bank (24 cells) and a charging voltage target of 57.6V (absorption stage). Charge voltage at 10C = 57.6 + ((10-25) x -5.0 x 24 / 1000) = 59.4VCharge voltage at 40C = 57.6 + ((40-30) x -3.0 x 24 /1000) = 56.88VCharge voltage between 25C and 30C is 57.6V

AC Source Settings

The next tab in our settings menu is the AC Source tab. In this section we are able to change important settings relating to either the generator or the mains voltage. We use the words AC Source rather than Generator, Grid or Shore power as the SP PRO can be used in a variety of applications which may include either of those AC supplies.

There are four sub-tabs within this section: • AC INPUT, relates to general settings that apply if either a generator or the mains grid are used as input power.• GENERATOR AUTO START relates to conditions that will start the generator automatically.• GENERATOR SCHEDULE START allows programming of scheduled run times for the system.• GENERATOR CONTROLLER SETTINGS is used to set up parameters that relate to the motor generator.

AC InputThis tab allows you to change the conditions under which the AC Input will be utilised by the SP PRO and transferred through to the AC Load.

Frequency setting (under the Inverter tab). If the AC source frequency goes outside these limits the SP PRO will immediately disconnect from the AC Source.

Max AC Voltage, 10 min avg. This setting is only used when it is a requirement of the connected Utility in a Solar Hybrid system. If this is not required then set it to the maximum value of 264V. If the 10 minute average of AC Source Voltage goes above this value then the SP PRO will disconnect from the AC source.

THE PRIMARY SOURCE configurations set the AC voltage and frequency limits of the AC Source input to the SP PRO. If the AC source falls outside these limits then the SP PRO will disconnect from the AC Source and run stand alone.

Min AC Voltage and Max AC Voltage. These parameters are set as a percentage of the Nominal AC Voltage setting (under the Inverter tab). If the AC source voltage goes outside these limits the SP PRO will immediately disconnect from the AC Source.

Min AC Frequency and Max AC Frequency. The parameters are set as a percentage of the Nominal AC


Doc #OI0005 Rev13 2016 | 29

Alternative Source. Configuration settings are used in place of the Primary Source settings and the AC Source Power setting (in Quick Start section). The SP PRO uses these settings when running a backup generator in a Solar Hybrid system, a second generator in an Off Grid system or shore power in a mobile installation.

The Alternative Source is selected when the configured digital input is active. The digital input is configured using the Normal/Alternate Input Power Selector parameter in the Inputs/Outputs section.

If a backup generator is required in a Solar Hybrid (On Grid) system, the optional Grid Fail Generator Backup Module will need to be installed.

Alternate AC Source Power sets the capacity of the Alternative AC Source. If the alternative AC source is a generator then set this to its continuous power rating. If the Alternative AC source is shore power then set this to the rating of the shore power outlet.

Min AC Voltage and Max AC Voltage. These parameters are set as a percentage of the Nominal AC Voltage setting (under the Inverter tab). If the AC source voltage goes outside these limits the SP PRO will immediately disconnect from the AC Source.

Min AC Frequency and Max AC Frequency. The parameters are set as a percentage of the Nominal AC Frequency setting (under the Inverter tab). If the AC source frequency goes outside these limits the SP PRO will immediately disconnect from the AC Source.

Extern. Contactor/CT. If a pass though current of greater than 63A AC (125A AC SPLC1200 and SPLC1202) is required then this setting is enabled when an external contactor and current transformer of up to 1000A AC is installed. The current rating of the external current transformer is entered in External CT.

See separate Installation instructions TN0057 available from the web site under the Support tab.

The AC INPUT LOGGING is a Quality of Service monitoring function which sets the Peak Voltage threshold at which the inverter will record a performance data event. (Peak Voltage of AC rather than RMS - 240V AC has a peak voltage of 340 V)

If you have particularly sensitive loads such as computers and plasma TVs, you may choose to set this to a low value to monitor power quality and record any unexpected high voltages coming from external supply sources.

These limits are important as higher voltages may shorten the life of lights and other appliances; while low voltage and frequency may overheat or overstress motors. The quality of supply to the load will be better with tighter settings, however this will also cause the inverter to disconnect from the AC Source and power the load from battery supply under what may be considered as “Normal Conditions”. If using in an Solar Hybrid (ON Grid) system and you observe the inverter disconnecting and then reconnecting, it may be possible that the AC Source is drooping when connected, in this case it can be rectified by lowering Min AC Voltage.The settings should not be made too tight or they will exclude the normal variation most incoming supplies exhibit - be that grid or motor generator supply.

Generator Auto StartThe use of an auto start generator in an Off Grid system is essential as a backup energy source in times of poor Renewable Energy production. In an Solar Hybrid (ON Grid) system the installation of an auto start generator can also provide excellent backup in times of extended outages without the need for oversized battery bank. This section explains how to use the generator to maximise battery life whilst obtaining the lowest operating costs on the system. The Generator Auto Start tab enables you to change the conditions under which the generator will start and stop. When a generator is started it will give first priority to service the AC Loads and any leftover available generator capacity will be used to charge the batteries.

GENERATOR LOCK OUT OVERRIDE

On Low Battery Voltage: As a safety net the SP PRO will always start the generator based on battery voltage, regardless of the battery SoC or the status of the Generator Lockout. When the battery voltage drops below the On Low Battery Voltage settings, the generator will start and run for the Minimum Run Time.

On Low SoC: When the On Low SoC is enabled and the state of charge falls below Start SoC at any time during the GENERATOR LOCK OUT period the generator will start and run until the SoC reaches Stop SoC or at the least for the Generator Minimum Run time.

The ON SoC NORMAL setting applies at times other than when other SoC Start Stop functions are active including during Generator Lock Out times. If SoC falls below Start SoC% the generator will be started and will charge until Stop SoC% or for Generator Minimum Runtime if Stop SoC% is reached before the minimum runtime has elapsed. By not allowing the generator to take the batteries to 100% avoids the generator from being too lightly loaded as batteries become full. It is more efficient to allow Renewable sources to fill the batteries to 100%


Doc #OI0005 Rev13 2016 | 31

The ON SoC NIGHT ASSIST state of charge control monitors the State of Charge through the highest usage period, usually during the evening. If the battery level has dropped to the Start SoC level at the appointed time (between the Start Time and the Stop Time)the SP PRO will start the generator and raise the state of charge until the batteries reach the Stop SoC level. This prepares the system for the night ahead.

By moving the bottom slider to the right you can access more settings in this field.

ON SoC RENEWABLE PREFERRED is designed to monitor the input from the solar array and, on a day when the renewable sources may be low in output, on a cloudy day or a day with no wind, start the generator at a lower state of charge to ensure the batteries do not get too low. This setting allows you to set a Start SoC percentage and a Stop SoC percentage that will keep the batteries in a “safe” state of charge.

If the solar input does not meet the usual consumption level you can start the day with a compensating charge that will enable the normal solar input to fully charge the batteries.

The necessity for this charge can be worked out in conjunction with a Selectronic Accredited Integrator (Australia Only).

The combination of all these settings should give you a battery protection program that should look something like this…….

When you get up in the morning, before the solar panels are working at their best, the generator runs for an hour or so while you are cooking, or heating the bathroom for the kids, and starts the day with a support charge (see SoC Renewable Assist).

Then it shuts down during the day when you expect that the solar panels will be carrying the load; then it may start again later that night when the night load is at its highest or if there has been a cloudy day and there hasn’t been as much solar input as you would have expected.

Throughout the whole day there is always the lower Generator Lockout Override “safety net” level that will not allow the batteries to get totally flat. A Selectronic Accredited Installer can help you arrive at the most fuel efficient program to suit your particular needs.

The above system of Generator Auto Start SoC Start and Stop levels prevents the generator from charging the battery bank during the batteries least energy efficient stage; the highest voltage with the least amount of absorbed amp hours. This reduces the generator run time, saving fuel.

This type of system is called Partial SoC control. A battery system will perform well in partial SoC conditions however it is desirable to periodically fully charge a battery bank and bring the SoC to 100% by allowing the charger to complete through to Float stage.

Referring to the section FOR 100% SoC, if Override Stop SoC is enabled then during the Normal or Night Assist times, the generator will continue to run and charge the batteries right through to Float stage. This will occur according to the Occurs Every setting. In this example it occurs every 7 days.


Doc #OI0005 Rev13 2016 | 33

The generator will also start if there is a persistent load on the batteries. Battery Load sets the level at which the generator will be started if the average load exceeds the preset level for more than 5 minutes.

Battery Load is the actual power being drawn from the battery bank. For example, if say solar is providing all the power to the site load, then no power will be coming from the battery bank i.e. Battery Load is 0 kW and the generator won’t be started.

On 15 min Load is similar to the previous screen except the settings take effect if the average load exceeds the preset Battery Load limit for more than 15 minutes.

We previously discussed mid point monitoring and its ability to help determine a battery fault. This screen allows you to choose if a mid point Voltage Error should start the generator. The generator will then perform a full charge of the battery bank and if equalise is enable will perform an equalise charge.

Generator Schedule Start

Some people have predictable times when they require a generator to run, such as when a regular plant watering routine requires pumps to run, the program contains the ability to predetermine four different schedules.

Each of the four Schedules (specified as Sched. x in the following examples) can be enabled or disabled.

Using Sched. x Day you can choose a day of the week, all weekdays, all weekends or everyday (All).


Doc #OI0005 Rev13 2016 | 35

A Sched. x Start Time

And a Sched. x Stop Time

The Sched. x Stop Time can be enabled or disabled. If the stop time is enabled the SP PRO will automatically turn off the generator at the end of the scheduled time or, if disabled, the generator will continue to run if a full charge cycle has not been completed or until all other generator turn off criteria have been met.

As an example, lets imagine you run a yoga class every Saturday morning and you wish to run a reverse cycle air conditioner for the period of the lesson. You may choose to run the generator during this period to prevent stress on the batteries. In this case the schedule would look like this.


36 | Doc #OI0005 Rev13 2016

By moving the slider to the right we find an INVERTER UNAVAILABLE SCHEDULE table. In the unlikely event that the SP PRO enters a shutdown condition whereby the inverter is unable to operate, the backup schedule can take effect in to start and stop the generator in addition to the existing Run Schedule. In the cases where the inverter is unable to operate, the AC Loads are powered directly from the generator via the built-in AC powered transfer contactor.

A typical example would be to run a freezer four times a day, for two hours – every day, say with the first as an example from 6 am to 8 am. This function can minimise food loss and provide a safer environment until the inverter shutdown cause is determined. The size of the generator fuel tank should be considered in the design.


Doc #OI0005 Rev13 2016 | 37

If there is an automatic generator permanently connected to the system the Generator Controller setting should be set to Enabled. This is highly recommended for OFF Grid systems If there is no automatic generator connected it should be Disabled.The Auto Start Available control allows 2 states. Follow Input allows you to switch the generator availability on and off with an input signal (normally 12 volts from the generator). This ensures that the SP PRO will not try to start the generator if it has become unavailable, e.g. starter battery flat or generator maintenance is being performed. Assume Always allows the inverter to operate as if the generator is always available.

Minimum Runtime determines the shortest time the generator will run. This is to ensure the generator wont start and stop too frequently.

The Pre-synchronised warm Up Time is the length of time, after the generator starts, before the generator is connected (Transferred) to any load.This is then followed by the Warm Up Time, the length of time, after the Pre-synchronised warm Up Time, before a charging sequence starts. Once synchronised, the AC Load is transferred to the generator during the Warm Up Time. The staged warm up sequence allows the generator to circulate the oil within the motor thoroughly and to allow the motor to reach operating temperature before being heavily loaded by the charger.

Cool Down Time disconnects the load from a generator for a period of time before shutdown to allow turbochargers to cool down before switching off. The Cool Down Time is overridden if generator is stopped using front panel push button.

Generator Lock Out provides a “quiet time” when the generator will not run unless the batteries get to a dangerously low level ..low level as set in the Generator Lockout Override (“Generator Auto start” tab). This setting is generally used for overnight operation.

Generator Control SettingsThe last tab in the AC Source section is the Generator Controller Settings


38 | Doc #OI0005 Rev13 2016

If the system design calls for very little, or infrequent generator input it is wise to run the generator periodically to keep the internal parts of the motor covered with oil and to keep the starting battery charged.

To use this feature Enable Generator Exercise and enter the Start Time the generator will run. Max Days determines how many days between generator starts. In this example the generator would start 30 days after the last time the generator was called for, would start at 18:00 and would run for the period set in Minimum Runtime.

GENERATOR REMAIN ON. This feature allows you to determine the minimum load will keep the generator running after a stop condition has been achieved, thus avoiding significant battery discharge. This term is expressed as a percentage of the inverter size. In this example the inverter size is a 6 kW and AC Load (50 - 100%) of rating is set to 80%. Therefore whilst the load on the system exceeds 4.8 kW (80% of 6kW) the generator will continue to run.

The Start output Delay setting determines the length of time after the generator run signal is initiated by the SP PRO, either by an external request, load requirement or by a battery charge requirement, before the generator start pulse is initiated.

Start output Time is the length of time a start pulse is sent. This output can be used in a pulse start/pulse stop type generator control.

Confirm start time is the time the SP PRO waits before deciding the generator hasn’t started. The SP PRO will try a total of three times to get the generator running with a 60 second pause between each attempt.

SIGNAL TIMING GRAPH The below graph depicts the relative timing for the Generator Run and the Generator Start signals.

When the generator is requested to start (A), the Generator Run signal is immediately asserted. After a delay equal to the Start Output Delay (A to B) the Generator Start signal is asserted (B) for a duration equal to the Start Output Time (B to C).

When the generator is requested to stop (D) the Generator Run signal is immediately de-asserted at the same time that the Generator Start signal is asserted for a duration equal to the Start Output Time (D to E).

Solar Hybrid Control SettingsThe Solar Hybrid Control settings are enabled when the Unit Application is set to Solar Hybrid (On Grid) and SoC Control is Enabled. They allow the system designer to determine when a defined amount of stored battery energy is utilised in conjunction with the connected renewable energy sources to optimise their use. Optimum use of the renewable and stored battery energy gives the SP PRO control over when and the amount of grid energy, if any, is required to power the connected loads. Using the settings below provides this flexibility.

PRIORITY 1 to PRIORITY 8The Solar Hybrid Control is made up of eight groups of identical settings with each assigned and labelled a priority level from 1 to 8 with priority 1 being the highest. If two or more Priority Schedules are active at the same time, only the highest priority settings will apply.

When a Priority schedule is active, all of its configuration options are active during that time. To see what Priority group is active and the limits that currently apply, see the SYSTEM REGULATION STATUS under the DATA VIEW NOW display..

The following configuration options are common to all of the Priority schedules

ACTIVATION controls when the limits and controls set for that Priority schedule become operational. ACTIVATION is divided into two sections:-

Enable Date and Time Activation setting. Use Begin Date and End Date to set the inclusive date range over which you want this Priority Schedule to be active. By default the range is all year and only requires adjustment if part of a year such as summer is required.Day selects the days of the week (Mon, Tues, ..., Sat-Sun, Mon-Fri, All) when the schedule to be active.Select the Start Time and Stop Time (in 24 hr format) for the schedule to be active. If the Stop Time is earlier than the Start Time then the Stop time is for the following day. If the following day is not selected in the Day or Date setting then the schedule will stop at midnight on the last selected day.

The digital input set in Activation Input is also used to activate the Priority schedule. This input will activate the Priority schedule regardless of the Date Time Activation. When set to “Rising” the Priority will be active when the input is high and inactive when the input is low. A “Falling” setting will control the priority in the opposite sense..

Both Activation types (Date/time and Digital Control) can be used together remembering if one or the other is active then the Priority Schedule will be active.

During Activation, the output set in Active Output will be energised and can be used to signal other devices or to drive other inputs in the SP PRO.

AC SOURCE controls the grid connection in three ways:-

Set the Grid Input Limit to the maximum draw from the grid supply. This limit will override the AC Source Power limit configured within the Quick Start settings. Any AC Load demand above this limit will be supplied from the Battery plus renewable energy sources (Battery / RE system).

This limit will only be breached if the AC Load demands more power than is available from the Battery / RE system or if the SoC Support Limit within the Priority schedule is reached.

Set the Grid Export Limit to the maximum power to be put into the grid. This limit will override the AC Source Power limit configured within the Quick Start settings.

This limit only applies to Managed AC Coupling or DC Coupled PV and must be set to the maximum (15kW for SPMC models and 30kW for SPLC models) when using Generic AC Coupled supply.

Enable Grid Disconnect to switch the SP PRO into standalone mode and operate completely on the Battery plus any renewable energy generation. No grid export or grid battery recharge is possible when the Grid Disconnect is Enabled

The Grid Disconnect setting will be overridden if the SoC Support Limit within the Priority schedule is reached or if Inverter Disconnect is Enabled.

The Grid Disconnect setting will be disabled and greyed out in all secondary inverters in a multi phase configuration. Only the primary inverter controls this function.

INVERTER CONTROL manages the AC Load Battery Support by controlling the amount and limit of battery support.

AC Load Support Limit sets the maximum AC Load power that can be supported from the battery bank when the SP PRO is synchronised to the AC Source (Grid) supply. This power does not include any contribution from AC or DC Coupled PV.

This limit is overridden to zero when the SoC Support Limit is reached.

SoC Support Limit sets the minimum Battery SoC that the AC Load Support and AC Source control will operate to. When the SoC Support Limit is reached any discharge demand on the battery is diverted to the AC Source (Grid) supply. When the SoC recovers by 20% of the battery’s discharge (e.g. back to 68% with a SoC Support Limit setting of 60%) then the AC Load Support Limit will once again apply.

Setting Inverter Disconnect to Enable switches the SP PRO into grid feed through mode and operate completely from the Grid and AC Coupled PV. No DC Coupled grid export, grid battery recharge or AC Load Support is possible during times when the Inverter Disconnect is Enabled.

The Inverter Disconnect setting will be overridden if the AC Source (Grid) supply falls outside AC voltage and frequency tolerance. There will be short break in supply (< 1.0 seconds) while the Inverter functions switches on-line to provide back-up power.

The Inverter Disconnect setting will be disabled and greyed out in all secondary inverters in a multi phase configuration. Only the primary inverter controls this function.

CHARGER CONTROL restricts the total AC power level and all the AC sources (if any) from which the battery is being charged. The settings under Charger Control are active until the Battery SoC drops to the Start SoC setting under Charger Override, at which point the settings under Charger Override become active. The Charger Override settings will remain active until the battery SoC reaches the Stop SoC setting.

The settings below apply to both the Charger Control and the Charger Override.

Battery Charging sets the charging source. The three options are:-Charging On: The SP PRO will comply with the requirements of the “Charger” Settings unless they exceed the Restricted Charge Limit setting. If the rating of the inverter is less than the Restricted Charge Limit setting then the inverter’s rated charge power will apply. This will reduce as temperature of SP PRO increases. The Grid Input Limit setting can also affect the charge power as this cannot be exceeded when charging from the grid. In summary the max charge power is the lesser of the following:• The Charger settings limit.• The Restricted Charge Limit setting• The inverter Charge power rating (temperature dependent).• Available power from all charging sources (Grid Input Limit –Load power +

renewable Power).The Charge Limit is displayed in the Data View > Now tab and is the lesser of:• The Restricted Charge Limit setting• The inverter Charge power rating (temperature dependent).Renewable Only: The SP PRO maximum charge power will be the lesser of the following limits. • The Renewable Power available for charging = Renewable – Load power• The Charger settings limit.• The Restricted Charge Limit setting• The inverter Charge power rating (temperature dependent).The Charge Limit is displayed in the Data View > Now tab and is the lesser of:• The Renewable Power available for charging = Renewable – Load power• The Restricted Charge Limit setting• The inverter Charge power rating (temperature dependent).It should be noted that Charging On setting with a Grid Input limit of 0kW operates the same as Renewable Only. This is because nothing can come from the grid during charging so charging can only come from renewable sources.Charging Off: Battery recharging disabled. This option will be overridden by any DC coupled solar charging sources when the AC Source (Grid) is disconnected or the Inverter is disconnected. It will be overridden by any Generic AC coupled sources when the AC Source (Grid) is disconnected.

CHARGER OVERRIDE settings become active instead of the Charger Control settings when the Battery SoC drops to the Start SoC setting. They revert back to the Charger Control settings when the Battery SoC rises again to the Stop SoC setting. Override Charge Limit settings have the same function as the Restricted Charge Limit settings.

AC Source limit during Override allows an alternative AC source limit to be used when the battery Charging is in Charger Override. Selecting Grid Input Limit (default value) means there will be no change to the AC Source Limit during Charger Override.Selecting AC Source Power means that the AC Source Limit will change to the AC Source Power setting in the Quick Start section under the Configurations Settings tab.

POWER OVERRIDE has no function within standard SP PROs. Contact Selectronic for details.

System Settings

In this section we will look at how the SP PRO works with the whole system. Whether the SP PRO will automatically recover from system faults, how it will alert you of problems and how it links with the computer and other communication devices.

The SP PRO is configured to recognise, and report, a number of events that can cause damage to the system, such as overloads, low voltage batteries. These events can be announced by a beeper within the SP PRO.

The Alarm - Beeper, may be set to:Enabled - Beeper will activate at any timeLocked Out - Beeper will not activate during the Lock Out period. Set a Lockout Start Time and a Lockout End Time. Note: Beeper will activate after lock out if existing alarm still persists.Disabled - Beeper will not activate for any alarms.

The AC source disconnect beeper provides an alert signal (five short beeps), once per minute, if the SP PRO is not synchronised to the AC Source. This is disabled by default and must be Enabled if you wish the system to signal that it is running on battery supply during grid outages.

The Year to Date feature of the unit is used to monitor the systems performance on an annual basis. You can choose the start date of that year with “Year to Date” Rollover Date. This could be the day you installed it, the first day of the year or another date that is relevant to the installation.

Through Detailed Data Log Interval you can choose how often an entry is made. A short interval of 1 minute will give more detailed information, but for only four days. A long interval of 30 minutes will give less detail but 120 days of records. A 15 minute setting records for 60 days and gives a good balance between detail and the number of days recorded.

The SP PRO has the ability to automatically attempt to recover from a fault situation. If System Fault Recovery is enabled the SP PRO will monitor the situation that created the fault, such as low battery voltage, and return the inverter to operation if the battery voltage returns to a suitable level.

Similarly if Unit Fault Recovery is enabled an internal problem within the SP PRO, such as overheating, is monitored and normal operation continued if the problem is resolved.


Doc #OI0005 Rev13 2016 | 43

The SP PRO can operate in a Multiple Phase configuration. The Multiple Phase setting in each SP PRO in these configurations must be set to either be the L1 - Primary controller, L2, L3 Secondary or Split phase - Secondary.

Any SP PRO that is configured as L2, L3 or Split Phase Secondary will have the Grid Disconnect and Inverter Disconnect functions in the Solar Hybrid Control disabled and greyed out. These functions are configured as required in the L1 - Primary SP PRO only which also controls these functions in all of the Secondary inverters.

Multiple Phase configurations require the use of external SYNC signalling and additional control wiring between each phase unit. Consult Three Phase installation instructions for further details including specific configuration requirements.

Systems with more than one SP PRO (two phase or three phase systems), have to be set to accommodate multiple SP PRO charging sources. For each SP PRO connected into the same battery bank, Enable Multiple Chargers is set to Enable.

Generic AC Coupling is only suitable for Solar Hybrid (On-Grid) systems and allows the grid connected solar to continue to supply power to the load and to charge the battery bank during a grid outage.This setting allows the SP PRO to “kick off” any grid tie inverter that is connected to the AC Load side of the SP PRO by ramping the frequency of the AC output of the SP PRO, This AC Frequency ramp is triggered during a grid outage when the battery voltage rises to 2% above the SP PRO’s active Charge Voltage target. When the battery voltage drops to 2% below the battery charge target, the output frequency of the SP PRO will ramp back to nominal frequency.

Frequency Ramp Limit sets the maximum “Generic AC Coupling” ramp frequency of the SP PRO above the “Nominal AC frequency”. For example if the Nominal AC frequency is 50 Hz and the Frequency Ramp Limit is set to 2.5, then the output frequency of the SP PRO will ramp to 52.5 Hz during a Generic AC Coupled frequency ramp. This setting is available once Generic AC Coupling is enabled

The ON front panel button is used to set the SP PRO to either IDLE (SP PRO is monitoring but providing no AC output) or ON (Inverter output is operating normally) By default, when the battery supply is connected, the SP PRO will power up in IDLE mode. With the Power Up Output Mode setting, this can be changed to power up in ON mode without having to press the ON button.

The SP PRO is designed to communicate with an external computer, either directly connected or via a communications device to a distant location.

There are two ports for this data transfer. When connecting through a modem DTR/DCD control signals allow the modem to signal the SP PRO that a modem connection has been established and when that connection has been dropped.

These control signals can be enabled through Port 1 DTR/DCD and Port 2 DTR/DCD while the speed of the data flow can be set with Port 1 Baud Rate and Port 2 Baud Rate.

When connecting directly with a computer through the USB port or data cables the Port 1 Baud Rate would normally be set at 57600 bps (default).

Note: Port 1 DTR/DCD is only provided for backward compatibility with previous SP PRO models and is no longer supported.

“Managed AC Coupled Solar” Section activates the AC coupled features within the SP PRO including the communications link with the KACO Powador or ABB Solar grid inverter. String Inverter selects the brand of grid inverter(s) that are connected to the SP PRO in the Managed AC coupled system. Only one brand of grid inverter may be connected to the SP PRO although any mix of compatible models within that brand may be used. The SP PRO Managed AC Couple Solar provides an efficient and convenient method of adding solar that is connected via the AC Bus.

Communications Port 2 is not available when Managed AC Coupled Solar is selected.

Selections other than Powador and ABB Solar may be listed for older versions of firmware or hardware and are provided for backward compatibility only.

Number of Devices sets the number of compatible inverters that are connected to the SP PRO in a Managed AC Coupled system. The maximum number of units that can be installed is five so long as the combined AC output of all connected compatible grid inverters does NOT to exceeding twice the AC Power output rating of the SP PRO (some exceptions apply based on battery size - See Islanding Power Limit setting below). Detailed installation and configuration instructions are available at www.selectronic.com.au

Grid Export Limit Monitor keeps track of any power that is being exported to the grid. If the exported power is greater than Over Export Trip Limit for a period of time that is greater than the Over Export Trip Time then the SP PRO instantly signals the connected grid inverters to turn off. Set these limits to suit the requirements of the connected utility and the SP PRO will ensure these limits are never exceededThese settings are ONLY operational with Managed AC Coupled Solar.

Fallback Power. All KACO Powador 00 or 02 series inverters built in 2014 or later can be programmed with a fail safe option called “Fallback” power. If at any time the KACO inverter loses communications with the SP PRO inverter, it’s output power will automatically drop to zero. This option is not used when ABB Solar is selected as they use a fail safe mode that is only programmed within the ABB Solar inverter.

Islanding Power Limit (firmware 8.00 and above). Limits the output power of all the connected compatible solar inverters when the SP PRO is islanding or Off Grid. This is useful in Solar Hybrid systems with small battery banks and allows the maximum amount of Solar to be installed and outputted when the system is connected to the grid by reducing this solar to a safe level when islanded (during a grid outage).This setting is automatically set based on the SP PRO model, battery size and brand of grid inverter (Powador or ABB Solar).

For more detailed information on Managed AC coupling please refer to the installation note IN0018 and IN0036 found on the web site www.selectronic.com.au

Input and Output Settings

The inverter contains 4 digital inputs, 4 relay outputs, 2 analogue inputs (excluding 120 V models) and 3 digital outputs, and these form the heart of the flexibility and sophistication of the SP PROs interface with the outside world.With these controls you can monitor when various set points are reached, switch on appliances when certain criteria are met, protect the generator from damage due to low oil pressure, schedule a watering system to switch on and off and many other functions.

Maximum voltage to any input or output; 60 VDC. See SP PRO specifications for full details.

Low Batt Shutdown Override Input function is also known as the “Just Go” control. In case of emergency, even if the batteries would normally be considered too flat to safely run the inverter, activating this input will force the inverter to run, until there is insufficient battery power left to maintain the load. This is considered essential if, say, phones or a fire pump MUST be operated.

When a second AC Source with a different capacity to the primary AC Source (Normal), is available to the system, use the Normal/Alternate AC Input Power Selector setting to set the input that you wish to use to select the alternate power level. The alternate source power level is configured in Alternative AC Source Power back in the AC Input section. When Alternate is selected, Solar Hybrid Control Priority schedules are overridden and no longer apply.

In some circumstances you may wish to prevent the SP PRO from exporting excess energy to the grid such as when the grid has failed and you have connected a diesel generator into the system. Using Inhibit Export Input in conjunction with the Normal/Alternate AC Input you can switch to a different power level and know that the SP PRO will not try to export power to the motor generator.

Shutdown Input, when active, will turn off the inverter section of the SP PRO and prevent any charging or discharging of the battery bank. Driving this input from the warning output of a Battery Management Systems (BMS) will provide a failsafe shutdown of the inverter. For Off Grid systems with auto start generators, the generator will start whilst this input is active and restore power to the site.

Shutdown Level selects the level at which the Shutdown Input is active


46 | Doc #OI0005 Rev13 2016

The Digital Control section is used to switch an output on or off with a digital input. For example, if the input that is set in Digital Control Input setting (Digital Input 2 in the example) is activated then the output set in Digital Control Output will be controlled (Relay Output 4 in this example) The output can be reversed using the Output State setting. In the given example a positive input to Digital Control Input 2 from an upper float switch could switch off a water pump via Relay Output 4.

In short you can control many different types of appliances or warning devices from digital inputs.The switching of a digital input is recorded as events on the event log and can be monitored by downloading data.

The SP PRO has two analogue inputs that can control the full range of output options. The analogue input is set in Analogue Control Input. An analogue input differs from a digital input in that instead of reacting to an on/off type signal as a digital input does. An analogue input reacts to a pre-programmed upper and lower voltage level which are set in Input Assert Level (on voltage point) and Input De-Assert Level (off voltage point).

As an example if a suitable moisture sensor was connected to Analog Input 1 the output from Relay Output 3 could be used to switch a watering system on and off depending on the moisture content of the soil.

A Selectronic Accredited Integrator can help you with specific applications that you may require.

To remotely start the generator set Generator Remote Start Input to one of the digital inputs to perform this function. There are 2 modes of operation: • Momentary Switch: If this input is pulsed on for less than 2 seconds the SP PRO

will see this as a pulse start and start the generator. A subsequent pulse for less than 2 seconds will stop the generator.

• On / Off Switch: If the remote switch is turned on and left on for at least 5 seconds, the SP PRO will continue to run the generator until the switch is turned off at which point the SP PRO will stop the generator.

The digital inputs can be used to protect the motor generator. One or more of the digital inputs can be configured to activate actions, warnings and shut down protection. In the Generator Available Input setting you can determine wether the generator is available for automatic control. This is particularly useful to prevent the generator from starting during maintenance or refuelling.

The Generator Low Fuel input will initiate an alarm when a suitably positioned sensor provides a warning that the fuel level within the fuel tank is low. The Generator No Fuel input will either stop the generator or prevent the SP PRO from attempting to start the generator when there is no fuel.

The Generator Fault input can detect signals from the generator control system to either stop the generator or prevent the SP PRO from attempting to start the generator when a fault is present in the generator.


Doc #OI0005 Rev13 2016 | 47

In Generator Outputs you can configure the Run and Start outputs to suit the starting requirements of the motor generator. The Generator Run Output will provides a start and run signal for a two wire generator controller. The Generator Start Output provides a start and stop pulse signal for three wire generator controllers. See Signal Timing under the Generator Controller settings.

The SP PRO can alert you when there is a problem that may prevent the smooth operation of the power system. This is achieved by configuring one of the outputs in the SP PRO to activate an external alarm, visual or audible, to alert you to a problem.

The Alarm Output field allows you to choose which output will be activated during an alarm condition. NOTE that the Alarm Output. is reverse logic and that the output is active when the alarm is off. This allows the Normally Closed (NC) contacts of one of the relay outputs to be used thereby triggering an alarm condition during a complete system shutdown and loss off Battery supply to the SP PRO.

The Alarm Type field lets you choose whether you will be advised of Alerts (warnings of potential problems), Shutdowns (events that have caused the inverter to shut down) or both.

The ABB Ground Fault Alarm Output can only be used in a Managed AC coupled system using ABB grid inverters. This output will become active when any of the ABB grid inverters in the system develops a ground fault.

The SP PRO can help you to manage the system by advising you when certain output levels have been exceeded. AC Load Energy Output selects the output that will be asserted when the daily energy consumption exceeds Energy Assert Level setting.

Similarly AC Load power output selects the output that will be asserted when the AC load on the system exceeds the power Assert Level for 30 seconds. Conversely the output is de-asserted when the AC load drops below the power Assert Level for 30 seconds.

For the purposes of demonstration let’s assume the system has been designed to provide 10 kilowatt hours a day and you consider any load exceeding 5 kilowatts is considered excessive.

In the example given AC Load Energy Output has been set to Digital Control Output 1 and this output will be activated when the daily usage reaches 9 kilowatt hours, as programmed into Energy Assert Level.

Set at this level the inverter will advise you when you are approaching the design limit of the system and allow you to choose if you wish to modify the power consumption for the remainder of the day. Similarly AC Load power output has been allocated to Digital Control Output 2 which will be activated if the AC load on the system exceeds the power Assert Level of 4.5 kW for 30 seconds.

External Regulator Bypass Output can be used to control a relay that will bypass the solar or wind generator regulator to allow the full renewable output to be forwarded to the battery or exported to the grid.

The External Regulator Control Output provides a signal to drive an external solar regulator


48 | Doc #OI0005 Rev13 2016

The AC Coupled Inverter Output drives an external solid state relay to control when the AC Coupled inverter feeds to the grid, local AC Load and battery bank. This is suitable for switching any Grid feed inverter. This setting is only available for Solar Hybrid (grid connected) configurations.

Any generic AC Coupling is best controlled via AC Frequency. See System settings Generic AC Coupling. The AC Coupled Inverter Output is a legacy setting retained for backward compatibility only.

Zero Percent Output setting is configured automatically when the ABB Solar inverter is selected in a Managed AC Coupled Solar configuration. This is for display only and cannot be changed.

If you are using an external contactor External AC Contactor Control Output provides a control signal for actuating the contactor coil. See AC Source AC Input to Enable the External Contactor/CT functionality.

This control is also used to provide a grid failure alarm. The output is active during a grid outage.

AC Source in Tolerance Output configures an output to become active when the AC source voltage and frequency are in tolerance according to the settings in AC Source / AC Input tab. This output can be used in a mutiphase configuration where it is a requirement for all phases to disconnect from the AC source when one or more phases are out of tolerance. Using this output L2-Secondary and L3-Secondary inverters can signal L1-Primary via the Grid Available Input that they are in tolerance before L1-Primary connects all phases to the AC Source.

High Battery Alert Output is initiated on the chosen output when the battery voltage reaches the Hi Battery Alert set point in the Limits section in the Battery Settings section.

Battery SoC Output initiates the chosen output when the SoC Assert Level reaches the programmed SoC Assert Level then switches off the output when the SoC De-Assert Level is reached.

If the SoC Assert Level is lower than the SoC De-Assert Level then the output will become active when the battery SoC drops below the SoC Assert Level then de-activate when the battery SoC rises above the SoC De-Assert Level.

If the SoC Assert Level is higher than the SoC De-Assert Level then the output will become active when the battery SoC rises above the SoC Assert Level then de-activate when the battery SoC drops below the SoC De-Assert Level.

The Battery Voltage Output setting is similar to the prior setting but is based on battery voltage instead of state of charge.

BATTERY CHARGER INPUTS are used in a variety of ways to help integrate the SP PRO with other renewable chargers. All work in a similar way but just move the charger to a different charging mode.

Care must be taken when using these inputs as improper use can prevent the charger working correctly. Consult a Selectronic Authorised Integrator for assistance.

The most commonly used would be the Float Stage Input.

Float stage input. Using the drop down menus you can choose which Digital Input you wish to use to control a function. Making this input high or active (> 10 V DC) will force the inverter charge controller into the “Float” stage of the charging process.

Float Stage Edge Consult the regulator manufacturer to determine the output signal the chosen regulator provides. The most common is the default of Rising edge.

Battery Charger Outputs also help with integration of external chargers but also be used to turn on or off various loads depending on what charge stage the charger is in. All outputs work in the same way, when the charger is in that charging phase, the corresponding output will turn on and subsequently turn off when no longer in that charging phase.

For example, you may wish to only turn on any pumping equipment when the charging process is nearing competition and whilst the charger remains in Float. By selecting the same output “Digital Control Output 3” for both Absorb Stage Output and Float Stage Output then the output will remain on during both of those charging stages.

The Timed Assert Output schedule similar to the generator run schedule is also provided for a digital output. This facility allows you to control the regular operation of appliances around the home. A typical example would be to turn on a watering system every night for a fixed period.


50 | Doc #OI0005 Rev13 2016

The final section controls the Solar Hybrid function allowing for a Backup Generator to be automatically controlled during times of Grid failure.

These setting must be used in conjunction with an optional external controller supplied by Selectronic. Full details of correct settings will be supplied with the optional controller.

Shunts Settings

The Shunts tab contains settings required to configure the connected DC current shunts that are used to measure the currents going in or out of the battery bank. The shunt readings are used by the SP PRO series to accurately calculate the state of charge of the batteries (System SoC). A shunt is not normally required to measure the SP PRO battery current as this is measured internally.

Both shunts are configured for their maximum current and the millivolts at that maximum current. For example for a current shunt rated at 75mV 100A, Max Voltage = 75 and Max current = 100.The table below describes the function of each of the Shunt Names SHUNT TYPE DESCRIPTIONSolar, Wind, Hydro, Charger

Unidirectional - Measures charging sources. Always assumes charging current so the polarity of the shunt is not critical

Load Unidirectional - Measure DC loads. Always assumes load current so polarity not critical..Dual Bidirectional - Measure DC charging and DC loads. The polarity of the shunt IS critical.Multiple SP PROs

Bidirectional - Legacy setting that was previously used in Off Grid, multiphase (three phase of split phase) SP PRO systems to measure L2 and/or L3 battery currents. The polarity of the shunt IS critical. Multiphase systems now use the System SoC shunt setting

Log Only Bidirectional - Used to measure and log a current that is NOT part of the system battery current measurement. This shunt type does to affect the battery current or System SoC.

System SoC Bidirectional - Used in multi phase (three phase of split phase) SP PRO systems and if selected then ONLY the current measured by this shunt type will effect the system SoC or effect the transition from Absorb to Float (see Battery Charger Section) . All battery currents measured from any other shunt type or from the internal SP PRO battery current reading will only effect the battery current reading for that individual SP PRO inverter within a multi phase system.

Direct SoC Input(Shunt 1 only)

This setting changes the function of the Shunt 1 input to an analogue input that measures the State of Charge (SoC) from the analogue output of a Battery Management System (BMS). The Voltage for 100% SoC sets the input voltage that generates a 100% SoC within the SP PRO and has a maximum setting of 100mV. If the BMS output is greater than 100mV for 100% SoC then a voltage divider will need to be inserted.When selected, this input overrides the internal SoC calculation.

1 AC SOURCE *When illuminated shows the presence of AC supply voltage from either a generator or the grid, whichever is applicable. This is powered directly from the incoming AC supply.

2 TRANSFER *Illuminated when an external AC supply is connected through to the AC LOAD output. If AC SOURCE is illuminated but not TRANSFER, it would indicate that either the AC supply’s voltage or frequency are beyond the set limits or the active Priority Schedule is set to “Grid Disconnected”. If the AC supply is a motor generator, check if it needs servicing; if the mains grid, check with your supplier for a problem, or for either, that the set limits are suitable. It is normal operation for this to flicker slightly.

3 AC LOAD *When illuminated, this shows the presence of AC voltage ready to supply loads. This is powered directly from the inverter AC output or AC supply.

DCThis screen gives you vital information about the state of the batteries at the time of viewing.The BATT SoC% indicates the actual capacity left in the batteries, just like a fuel gauge in your car, and will help you make decisions about the power consumption for the rest of the day. Similarly the Battery Voltage gives a rough guide to battery condition.

The next four readings give you an overview of what’s going into and coming out of the batteries. Inverter Current shows the amperage being used by the SP PRO to run AC loads or the amperage being contributed to battery charging if the generator is running. DC Battery Current is the nett amount going into or out of the battery pack. If the Solar Current is greater than the loads a positive figure will be shown while if the loads are greater than the combination of charging sources a negative figure will appear. Load Current is the measurement of DC loads monitored by the Load shunt.

Charging Mode indicates the active stage - Initial, Bulk, Absorb, Float (Short or Long Term) or Equalise Charging.

AC SOURCEThis section displays the contribution and condition of the mains grid or motor generator that is connected to the SP PRO AC source input.

Power reading is the input power in kilowatts.

Power (5min Average) is the average power in kW over the last 5 minutes.

Voltage is the RMS AC voltage.

Current is in Amps.

Available Power is the difference between the Power reading and the AC Source Power setting in the SP PRO. The SP PRO will automatically reduce the charge power to the batteries or draw power from the batteries as required to keep the AC Source power below the AC Source Power Setting.

Network Power Meter displays the total power as measured by an externally connected three phase power meter. Contact Selectronic or visit the web site for more information.

INVERTER ACThis panel is similar to the preceding panel except that it shows the Inverter Power and Current from the inverter.

AC COUPLED SOLARThe panel shows the total Power and individual output powers from each of the connected compatible grid Inverters. These are listed as Power #1 through to Power #5 along with the grid inverter’s model number (when connected). If the SP PRO has lost communications with the grid inverter or the grid inverter has gone to “sleep” at night, the message “Inverter Offline” is displayed.

Percentage Power is the maximum output of all the connected compatible grid inverters as a percentage of the Total Capacity. As an example if the Total Capacity is 10kW and the Percentage Power is 50% then the maximum output from all the connected grid inverters is 5kW.

The Percentage Power may be displaying less than 100% even though no power limiting is required. This is because the SP PRO intelligently uses predictive algorithms to determine the optimum value based on the available solar input to the grid inverter at that time

Total Capacity is the total rated power of all the connected grid inverters. This reading will drop to zero when the grid inverters go to “sleep” at night.

SYSTEM REGULATION STATUSThis panel shows the control status and power limits active within the SP PRO mainly for the Solar Hybrid Control configurations. These power limit values also hold true for Off Grid and Mobile. These values are the configured maximums defined by the Solar Hybrid Control however the system may not be capable of achieving these values and can be overruled.

Solar Hybrid Active: Shows the active Priority Schedule (1 - 8), Alternate or None. • Priority 1 to Priority 8: Indicates the currently active Priority Schedule.• None: indicates that no Priority Schedules are active at this time. • Alternate indicates the Alternate AC Input is active and all Priority Schedules are overridden.

The items listed below are the configuration values and limits for the Solar Hybrid Active

AC Source Input Limit: The maximum AC Source (Grid or Generator) input power allowed for AC Load or Battery Charging at this time. This limit will be breached if the AC Load demands more power than this limit and AC Load Support Limit combined.

Grid Export Limit: The maximum Grid export power allowed at this time. This limit will always be 0,00kW when the Unit Application is set to Off Grid or Mobile.

Charge Limit: The maximum Battery Charge power allowed at this time. The Charge Power will be capped at this value regardless of the charge power required by the SP PRO Charger (See Configuration Settings > Charger). The Charge Limit will display the maximum charge limit of the SP PRO when either:• No Priority Schedules are active• The Restricted Charge Limit setting in the active Priority Schedule is greater than the maximum

charge limit of the SP PRO

AC Load Support Limit: The maximum AC Load power that can be taken from the battery bank. This limit will be breached if the SP PRO is not synchronised to the AC Source input.

Battery Charging: Shows the status of the SP PRO Battery Charging function: • Restricted Charge, The Charge power is restricted to the Charge Limit within a Priority

Schedule• Charger Off. The Charge is off and wont charge the battery. The AC Load Support Limit is still

active• Renewable Only Allows battery recharging from both AC Coupled or DC coupled renewable

sources but not from the AC Source (Grid) supply.• Normal Charge. This is displayed when no Priority Schedules are active.

Inverter Disconnect Status: Shows if the inverter within the SP PRO is active or disconnected.• Inverter Active: all the normal charging and support functions operate.• Inverter Disconnected: There is no AC Battery Charging (AC Coupled or Grid), AC Load

Support, AC Source Input Limit or any Support or Export from DC coupled solar. If the Grid is interrupted, the Inverter switches on after a short break in supply (< 1.0 seconds) to provide back-up power.

Grid Disconnect Status: Shows if the Grid is allowed or is being kept disconnected • Grid Allowed: The SP PRO will synchronise to the grid when available.• Grid Disconnected: The SP PRO will not synchronise to the grid even though the grid maybe

within voltage and frequency tolerance.If Inverter disconnected is active during Grid Disconnected, the Grid Disconnected will be overridden.

Power Override Target: No function within standard SP PRO units. Contact Selectronic for details.

Recovering Message: When the battery State of Charge (SoC) reaches the SoC Support Limit within the active Priority Schedule the highlighted message “Recovery” appears within the affected reading. When the SoC recovers by 20% of the discharge (eg from 60% to 68%) the displayed readings return back to normal.

DC TOTALSThis panel is a summary of today’s totals of inputs and outputs through the battery pack. DC Energy In is compared to DC Energy Out to arrive at DC Energy Net and the results are recorded in kW hours.DC Inverter Energy is a total of the work the inverter has done, whether that is supplying a load or charging.If you wish to monitor the day to day performance of the system Time That Float Was Achieved Today can be compared with yesterdays in the DC HISTORY tab. This can be a handy comparative reading. You can record daily how long it takes the system to replenish the previous days usage.

AC TOTALSThis is also a summary page, but this time of the AC kW hours through the system. AC Load Energy records the total power consumption by the site during that day.AC Input Energy shows the total contribution by the generator or the mains grid, while Hours of AC Input records the running time of the generator or the length of time the mains grid was connected to the SP PRO.Inverter Run Time is the length of time the inverter has run today – this should be all the time unless you have programmed in an Inverter Lockout period.In grid connected systems Export Energy is the total power the system has contributed to the mains grid in that day.

DC PEAKThis screen records the peak power level that has passed through the shunt(s) that day. Not Applicable means the shunt isn’t configured for measuring renewable.

AC COUPLED SOLARAC Energy (kWh) generated by the Managed AC coupled grid inverters.The Individual energy readings (Energy #1 etc) are not available when ABB grid inverters are used in a managed AC coupled system.

Today TabThe TODAY tab gives you data about the system for the current day.

DC ENERGY RESETTABLE is like a trip meter in your car. When reset this records DC energy in and out of the system and gives a net total.

RESET ON: shows the date when last reset so you can calculate how many days have elapsed. By clicking the Reset tab all totals in this reading are zeroed and accumulation of data starts again on the date of the reset.

HOURS OF FLOAT records what time float was achieved on the previous day and how much time has been spent in float since installation.

This data can be used for future system improvement design. If the system never reaches float, you may need to increase the solar array size, if the system regularly enters float before lunch you may be able to consider adding extra “luxury” loads to the system.

This panel gives a picture of the effect that Shunt 1 has had on the system. For the sake of clarity we will assume that Shunt 1 measures the solar input. This, then, records the solar contribution to the system since the system was installed. Once again you can compare today’s solar input with other averages to see if you’ve had a good or a bad solar day.

As with the previous screen you can collect data over a period you determine with the use of the Resettable feature.

The Total Accumulated is all the solar input to the system since installation.


62 | Doc #OI0005 Rev13 2016

This panel is the historical record of the Shunt 2 and its effect on the system, either through a renewable contribution, if it is measuring input through a wind turbine or micro hydro, or as a deduction through DC loads. In the case shown, DC Loads.

This panel shows historical data of all of the DC energy that has passed into or out of the inverter.

This panel also gives you the ability to accumulate this data from a date you determine. By pressing the Reset tab all totals in this reading are zeroed and accumulation of data starts again on the date of the reset.

A particular feature of this panel is the ability to compare the previous days total with the averages over a week, a month or a year.

Technical Data Tab

The TECHNICAL DATA tab provides you with information relating to maintenance and updating the SP PRO.

The technical data displayed under BATTERY is described below.

Current is a measurement of the current in the battery bank. A positive (+) value, the battery is charging. A negative (-) value, the battery is discharging.

Sense Voltage is a measurement of the battery voltage at the battery terminals (when the battery sense/pre-charge wiring is installed)

Target Charge Current and Target Charge Volts Show the present temperature compensated charge current and voltage of the SP PRO battery charger.

DC Inverter Voltage is a measurement of the battery voltage within the SP PRO

Power is the amount of power presently drawn from the battery bank and is used in conjunction with Cable Loss to determine its significance.

Midpoint Voltage is a measurement of half the battery voltage at the battery terminals (when the battery sense/pre-charge wiring is installed) If this value is not half the Sense Voltage then the batteries need equalising or there is a faulty cell.

Midpoint Error is a measurement of the error in the midpoint voltage as a %.

Cable Loss is the amount of power that is dissipated in the battery cabling, fusing and terminal system. A high reading could indication a problem with the battery terminals, battery connection to the SP PRO or inadequate cable sizing.

Cable Loss % is the Cable loss as a percentage of the Battery power at that time.

SoC % is the State of Charge of the battery bank. 100% SoC is a full battery.

Days to Recharge and Days Since Recharge - If Periodic Recharge is enabled these readings track the days since the last battery recharge and how many days before the next battery recharge.


66 | Doc #OI0005 Rev13 2016

Charger Lockout Requested indicates when the charger is off and there is no charging from the SP PRO.

Charge Efficiency Index is an internally adjusted factor that is used to constantly calibrate the State of Charge calculation within the SP PRO. It also gives an indication of the battery health with a value below 0.8 suggesting that the batteries may need replacing. A normal value is between 0.9 and 1.0

Days to Equalise and Days Since Equalise record how long since the batteries received an equalising charge and how long before one is due. When an external charging source raises the battery voltage to the Equalise voltage for the Equalise period the SP PRO will see this as a completed Equalise Charge.

Charging Mode shows the stage of battery charger in the SP PRO. This is the same information as shown on the front panel of the SP PRO.

AC Power is a measurement of the real power being passed through the inverter between the DC sources (Battery bank and DC coupled charging sources) and its AC output. A positive (+) value, the inverter is charging the battery. A negative (-) value, the inverter is supporting the load from the DC sources.

Reactive Power is a measure of the VArs being provided by the SP PRO.

Apparent Power is a measure of the inverter’s AC voltage x AC current (volt amps).

Power Factor is that of the inverter AC output. This is not a measure of the power factor of the load except when the SP PRO is in stand alone (not synchronised to the grid or a generator) and with no AC coupled solar input.

The TEMPERATURE CONTROL panel displays the temperatures of various components within the SP PRO under the present operating conditions. This will assist support personnel to determine the cause of thermally related system issues.

The INPUTS AND OUTPUTS panel monitors the status of the digital and analogue inputs and outputs. Active is ON and Inactive is OFF.


Doc #OI0005 Rev13 2016 | 67

In the INVERTER section we show you the Software Version and hardware that is currently installed in the inverter. From time to time, as Selectronic designs new features for the SP PRO, new revisions of software may become available from our web site. Generally, there is no need to update the SP PRO unless you need the new features made available.

Total Run Time tells you the total number of hours the inverter has run.

Factory Set Options displays the configurations that have been set in the factory. These settings cannot be changed.

The SP PRO monitors the life-span of certain components within the inverter. By advising you of the amount of Capacitor Life and Fan Life that have been consumed SP LINK allows you to plan for long term maintenance at a time that will not inconvenience you.

The AC Solar panels (#1 through to #5 when connected) display all of the data fed back from each Managed AC coupled grid connect unit.

The “RS485 Device Address” shows the Address that has been configured in that particular grid inverter. For KACO inverters this is address 1 to 5 for AC Solar #1 to AC Solar #5 respectively. For ABB inverters the RS485 Device address is 2 to 6 respectively.

When ABB solar grid inverters are connected to the SP PRO, there are 4 readings that are not available from the ABB solar gird inverter. AC Energy today, AC current, DC power and DC current.

If the SP PRO has lost communications with a grid inverter or the grid inverter has gone to “sleep” at night, the message “Inverter Offline” is displayed in all its readings except AC Power Peak Today

Certain readings within the SP PRO must be correctly configured at the time of the original setup. These include the time and date, an approximation of the state of charge and that the current shunts are zeroed.

Service Settings


Doc #OI0005 Rev13 2016 | 71

Time and date

To ensure that various timed functions within the SP PRO, such as generator run schedules, perform as expected it is important to have the correct date and time recorded in the SP PRO. You have the option of automatically uploading the time and date from the computer – including the facility to allow for an offset if the computer is set to a different time zone to the area of installation – or to manually set the time and date.

If you are adjusting the date manually click on the circle adjacent to MANUALLY SET DATE / TIME and use the drop down menu to select the correct date. The time can be set by clicking on the hour or minute section and use the up/down arrows to adjust.

When you have completed adjustment click on SET SP PRO TIME to record the change.

Battery SoCWhen first setting up the SP PRO an initial estimation of the state of charge must be programmed to enable the SP PRO to facilitate all the functions that are determined by the state of charge measurement from the first day. As the period of operation increases any small error from the original estimation will be corrected.

Expansion CardThe current status of the EXPANSION CARD is displayed. The SP PRO can be set to use (Enabled) all the connected functions from the expansion card like shunts and battery temperature sensor or to ignore (Disabled) them. By default the Expansion Card is enabled.

Settings PasscodeThe Settings Passcode is only used to change configuration settings within the SP PRO. A separate passcode (Login Passcode) is used to connect to the SP PRO. If you are concerned that the standard Settings Passcode does not provide the level of security you desire for changing settings, you can change the passcode in the SP PRO to one that is uniquely yours.

Please note that if this Settings Passcode is lost or forgotten it can only be reset by a procedure that requires someone to be on site.

If you require assistance resetting the passcode please consult a Selectronic Accredited Integrator.


72 | Doc #OI0005 Rev13 2016

Zero Shunts

To accurately measure and calculate inputs and outputs to and from the batteries the SP PRO needs to start its measurements knowing what is Zero. To set this parameter you must ensure all inputs and outputs are switched off – that is no solar, wind or other inputs coming into the system and all DC loads are switched off – then the ZERO SHUNT 1 and ZERO SHUNT 2 buttons should be pressed.

The figures above the buttons indicate what the on board computer in the SP PRO perceives the relative current to be before zeroing.

Fan Type

The cooling fan within the SP PRO is a long life, high quality component. As the control section of the SP PRO calculates the hours of life left in the fan (along with other components) it is important that the fan – when it is eventually necessary – is replaced by an authorised spare part. However we are aware that components become obsolete and other fans may need to be used, so we have allowed settings for 4 different fan types. These settings are based around all the fan types available at this time and we will clearly mark any replacement fans with their fan type as they become available.

AC Safety Monitor

The AC INPUT SAFETY MONITOR assesses the presence of an earth/neutral link in the generator or the mains grid connected to the SP PRO and will prevent this source of power connecting to the system if it is not present. This important safety feature is included for the protection and should never be ignored. This being said there are certain marinas around the world that have isolation transformers in their shore power connection that will trigger this feature. If you have the SP PRO installed on a boat and encounter this situation it is possible to disable this function temporarily to allow you to use the shore power connection. An alert will periodically sound to remind you that this safety feature is disabled.


Doc #OI0005 Rev13 2016 | 73

Request Battery EqualiseThe BATTERY EQUALISE display shows whether the SP PRO will perform an equalise charge when it next achieves Float (Equalise Pending). Pressing the button will toggle between Equalise Pending and No Equalise Pending. Pressing the button will also stop a current Equalise process.

Login Password

The Login Password is only used when connecting to the SP PRO. A separate password is used to change configuration settings (Settings Password). If you are concerned that the default login password does not provide the level of security for any access to the SP PRO, you can change the Login Password in the SP PRO to one that is uniquely yours.

Like the Settings Passcode, if the Login Password is lost or forgotten it can only be reset by a procedure that requires someone to be on site.

SP LINK will automatically update the Connection settings in Site Information when you set the new Login Password.

AC Solar Link TestUsed for commissioning or diagnostic of the communications link between the KACO Powador or ABB solar inverter(s) and the SP PRO in a managed AC coupled installation. AC solar Link Test provides a count of any errors in the link.

When the system installation is complete and all inverters are powered up and running, click “Reset Counters” then wait for 5 minutes. All connected grid inverters should ideally read 0 showing there are no issues with the communications link. A link error count of 4 or less per minute is acceptable although it is recommended that the installation be checked to ensure there are no underlying issues such as the incorrect setting of the RS485 termination resistor on either the SP PRO or grid inverters.

Setting Charge Efficiency IndexThe Charge Efficiency Index will automatically adjust itself in the SP PRO but a number of faults in the installation could cause it to become erroneous (including poorly calibrated or installed DC current shunt or failing batteries). For a correctly installed system with new batteries the index should be between 0.900 and 1.000. If it is a long way out of range, rectify the system fault then reset it back to 0.950.

Setting For Poor Grid QualityWhen the SP PRO is connected and synchronised to an external AC source (grid or generator), it is actively improving the quality of the AC source waveform. If the AC source waveform is particularly distorted then the SP PRO may shutdown from a “Synchronous Overload Shutdown” condition. Setting the Grid Quality to Poor will reduce the sensitivity to this distortion and allow the SP PRO to operate as normal.

SP LINK | Alert Messages

Appendix One Alert Messages

The SP PRO is continuously measuring and monitoring the power system to ensure correct system operation at all times. When the SP PRO detects a problem with the power system it then:1. Displays a message in the “Attention Required” area in SP LINK (In the Data View - Now tab).2. Creates an entry in its data log memory. This data can be downloaded from the SP PRO and viewed in the EVENTS tab of the Performance Data Viewer.

The table in this section outlines all the SP PRO ALERT type event messages, the most likely cause and possible remedies.

System - AC Load exceeding AC Source plus Inverter Rating

When the inverter is connected and synchronised to the AC source, the load on the system is exceeding the rating of the inverter plus the specified AC Source Power limit. Under this condition the AC source Power limit will be exceeded. This could cause an overload on the AC Source and the load should be reduced.

Turn off some of the loads connected to the system. If you need to continue to use high loads on the system then contact your installer to upgrade the size of your system.

Config. Settings > AC source Power.

System - AC Load below AC Source plus Inverter Rating
